A sports injury is considered minor if it prevents the athlete from participating in practice or games for fewer than seven days. Historically, around 77% of all injuries in softball are minor, but recent data suggests that that percentage could be declining as more athletes sustain major injuries on the field. A random sample of 136 softball injuries show that 90 of them are minor. Use this data to test the claim that the percentage of all softball injuries which are minor is now less than 77%. Use 0.01 as your significance level.You must provide the p-value and an interpretation specific to this problem to receive credit.
